Billy Crone is a frequent guest with Gary Stearman and Mondo on Prophecy Watcher. His books and videos are very interesting. L.A. Marzulli is pretty good also. It's amazing the stuff you can learn by being exposed to their material.
Correct! Yes, Marzulli is certainly in that realm. I met him a few years ago at a small conference. He is great at making himself available for discussion.
